Oracle Database Tips by Donald BurlesonMarch 16, 2015

Question:  How do I use the 12c DBMS_QOPATCH package to check my patches?

Answer:  Prior to Oracle 12c, it was not easy to List Oracle patches   In 12c and beyond, you can use the DBMS_QOPATCH package to list all patches.

Rampant author Laurent Schneider, author of the book "Advanced SQL Programming has these notes on DBMS_QOPATCH.

"One of a cool new feature in Oracle 12c is the ability to query Opatch. Oracle offers a set of tables and a PL/SQL package to query the Oracle Inventory.  With the DBMS-QOPATCH procedure, you can query the inventory to know if a one off patch has been deployed, which components have been deployed etc.  Tables related to this feature include:


This is the base of the feature which is accessed through a PL/SQL package DBMS_QOPATCH. The DBMS_QOPATCH package has many functions, including:


For example, if we execute the GET_OPATCH_BUGS (which provides bugs list in a specific patch or for all patches), the result is a XML output:

SQL> select dbms_qopatch.GET_OPATCH_BUGS from dual;

We also see these DBMS-OQPATCH package invocations:

SQL> select dbms_qopatch.GET_OPATCH_FILES from dual;

SQL> select dbms_qopatch.IS_PATCH_INSTALLED from dual;

SQL> select dbms_qopatch.GET_OPATCH_LIST from dual;

The Oracle DBMS-OQPATCH documentation has complete details on using the 12c DBMS-QOPATCH package.
